Be t knownthat I, THOMAS SEELY a citizenY ofjthe United States,V resiin'gat Maiden, in the county oi' 7S' iid State of Massachusetts, have'inventedeertain Improvements in Controlling Mecia nisms for'laeking-Machines, of'vvhich fthe followingdescription, in connection with the accompanying drawings, is a specification,

like reference characters onrthe drawings indicating like parts in the Ysevera-l figures. The invention to be hereinafter described relates to lasting machines, and more par tionlarly to that type of iastin machines which is adapted to YWork ond VVerent por tions of the upper materialssusacessiveiy as described in United States lf"atentV No. iijl-i, dated June 15, 1897, i

In machines of this type, devices such as pincel-s are actuated to griprendpull or updraw the upper materials and overdraw or lay them upon the innersole, and e YWiper is usually employed in connection withV Vthe pincer devices to engage the upper materials and press or'rvipe them smoothly upon the innersole. The upper materials are secured in lasted position b v fastenings, such as tacks, which are fed successively to fas' toning, inserting or tack driving means. During the lasting and tackY driving operations on this type of lasting machine, the shoe is ordinarily heid in both hands of thc operator While his foot maintains the start ing and stoppingtreadle in position to continue the machine in operation. Y Y

Then a shoe has been lasted and While the operator reaches for another shoe, itis expedient that the machine continue in operationyand in practice this is the usual oustoin. During this idle operation oi' the mnehiue, lossV of -tacks is liable tooecur, hecau in the absence ot means to prevent it, the tack-feeding means and driverV remain in operation when no shoe is in the machine. V Y Y VVIn prior machines of this type, provision has heenniade for suspending the operation of the tack-feeding means when a shoe is not in position for the lasting operation and permit operation of the feeding means when a shoe is placed in the machine. In some of such cases the driver has remained Specification Vof Letters ateut. Patente Sgpt. 1G, 191 8.

in operative condition, or if heldin inoperativdcondition, it hasY been freed by the act oiplaeing the Work in theY machine. An important Vicaiture ofthe present invention consists in the provision of means which Vnormally lock the tack-feeding means and the tack driver when a. shoe is not presented for the lasting operation, and Which is positioned by the introduction of the Work for unlocking the tack-feeding means and moving parts into operative relation for automatically uniocking the tack driver.

With respect to this feature of the inl vention, a unitary member is under the con; trol of a wor -engsging part, which serves to positionY the member to permit the taekfeeding means and the tack driver to'he autonmtically operatori when a shoe is presented to the machine1 but VFails to move said member to permit such operative een dition when Vthere is no shoe in position to he lasted.V Y Y Another important feature of (he invcn tion consists of a controlling member for the tncicfeeding and driving means movable by the work to permit operation of the tack feeding means, and autmnaticall)v Ymovable after Ait has been first moved by presentation of the work, to unlock the driving means.

The above features of the invention and others not hereinheore specified, as well as certain novel constructions Vand combinations of parts, will now he described in con section with a machine of the type set forth in the application of Thomas Il. Seely, Serial No. 60,309, filed November 8, 1915, of Which the present application is a Vdivision, hut it is to he understood that the invention isnot 'to he considered as necessarily restricted in its application to this type of machin@ nor to the particular details described in making disciosure of the invention.

In the drawings z- Figure l is a perspective View showing a lasting machine with the present invention appliedthereto, only such parts of the lasting machine being illustrated as are desirable in order to show theeonnection and relation of the present invention therewith:

Fig, 2 is an enlarged detail partly in scc tion, Showing the tack driver and driver lock, and associated parte;

Fig. 3 is an enlarged perspective detail relating to the taek'saver;

Fig. -l is a sectional and part ele 'atioual detail oi the turk earrier `alide and wiper mechanism 5 Fig. 5 is a detail in perspeetive showing the relation of parte when the taeleteediug means is locked or prevented from t'eediug tacks; and

Fig. 6 is :1 plan view in detail showing the member for eontro'llin the locked or unlocked eondition ot" t 1e t:ir-'li-fee(li1xg means and tack driver.

The head. trame ot the machine may he ot any character suitable for supporting the operating partel of the machine, and as Shown, conaistfs oic the (fasting or otherwise Suitahly formed frame 2 carryingl the usual driving shaft 3, Fig. 2, which may he driven from any convenient Source ot power. The uSual incer lnechaniem and the operatinpr means herefor are not herein shown ae they mayv be of any character yauitahle to the vvork to he done, or like the device` deeierihed in the application ot which thiny in a division. After the piueer-grippinpr and overdearring.;` moveinento have placed the upper over the, inneraole` or in treating certain portiom` ot the upper materiahl, as' ahout the heel for instance. the upper materiale? mayY lie luid over and upon the innen-#ole by a wiper. :i z well iinrlei'-torid hy tlu'eie @killed in the art. This wiper may be ot any 'haraeter euited to itS pnrpoaeD hut as illustrated in the preesent inatauce of the invention, the wiper mounted 'for movement in an inclined path rolativel \Y to the edge ot' the shoe to eonform to the direction of plaitrf that may he made hy the piueer meel'mnisin, as: fully de- Serihed in the llnited Stattw ltetterr` Patent to Bates, No. lflflttl, dated .lune i9. 191:71. Vhile thin` character of wiper and it. uetion may he advantageoualy emplrrverl in i-uolne cases, the invention herein is not dependent upon the wiper, but auch wiper may he omitted and dependence placed upon the usual tack carrier Slide t'or wipingr the upper materials into laated pooitioin as will he readily understood.

ln the present eml'iodiment of the invenH tiointhe tach carrier slid@l Tl carries the tack carrier 71') havingV un opening` 'iti therethrough`r Vfor receiving a taek from the tuck feeding lucana. as will preeentl'v be deA scribed, and presenting the tack to the driver. In operation, the rilide har ia ree-iprocated to carry the tack carrier hach and forth, and when the tack carrier reaches a suitable ponition in its; reurw-u'd movement. a tack is transferred from a raeewaf.Y into the aperture 76 of the tack carrier and then the tack carrier i@ moved forward into proper timed relation to the operation el the pincers, and may art to wipe the overlaid upper onto the inneraole. A driver then forces the tack carried in the aperture ot' the tack carrier through the upper materials to Secure them in lasted position.

Pivotally mounted at, 77. Fig. l. on the tack carrier 75, is the wiper TS which will partake oil the reciprot-ating` movi-nient oi' the tack carrier t5; and in order that the wiper 78 may he given the inclined direction already described, the rear end portion of the Wiper in provided with a roll T9 which engageol a U-guide 8H, the poeition ot' whieh is under the control of an arm Si, Fig. h connected to the swing member H2. Fig. t,` substantially as more fully explained in the patent to BatesA` to which reference has` het made.

The tack 0r faatenintra which are to Jecure the up er in lasted poaitiou, are euplied throng a Suitable raoeway 85., and deivered to a tack Separator SG, iFig. it. whien has a iieeiiiroeating movement ieio.-ff v the end of the raceway to det aeh therefrom Vingt)- and deliver to the taek carrier. a` tart: to he placed in position for the driver.

Reciprocating movements are imparted to the tai-k Separator 8G hy the raf-k and aegment 87, S8, reepectivelyn the latter heine formed all part 'of a yieldinfr memher SJ, ev usual, and normally under the influent-e of :i Spring againet the teuaion of vvhifh the yielding member 8f) may he appropriately' moved by meane` ot a cam 189 on the taek carrier Slide and a roll 190 on the viel-lino memher S9, to effect reeiproeation ot the turk separator 8F. Tn the present` form ot the invention, the yielding member S9 i-` composed of two parte? the segment carry.- ing portion and the operating portion .91 said two portions ol the member R9 being substantially otthe construction heretofore common in this clase of devices. and the eon` struction being .ffueh that while the tat-,k epr arator Sti may be reeiproeatedto detach a tack trom the raeeway and deliver it to the tack earrier when auch Separator movement ie not ohetrueted, yet when there ik oh'itruetion to the tack Separator movement the t wo portions ot the member Si) may yield to permit the tack eeparator to remain at reet. The general eonetruetion and operation of the pa rt."y relating to the tack nepurator and tack Supply muy he ne heretofore common in the art.

then the operator han#` finished laalinfl one Shoe he placel it upon u Suitable rack or reeeiver and rwiehea4 t'or another Shoe. During thi1 tiint` he maintains his: toot upon the Starting treadle, with the result that the machine continuel: in operation. To prevent a loge oi taekai it iff, expedient that means he provided to interrupt the supply of taeke when there is no shoe in the machine during.;l the operation thereof and it i-1 likewiee desirable that-upon presentation of the shoe to the lasting instrunientalities, the individual supply of tacks to the tack driver be perinitted and that the tack driver itself be free to perform its driving function. To these ends, the present invention conteniplates the provision of means whereby when there is no shoe presented to the machine, the tack feeding,r means and Vthe tack driver shall be'locked from operation, and that when a shoe is placed in the machine or presented for the lasting' operation, the tack feeding means shall be unlocked and that parts be Vplaced in operative position for automaticaily unlocking the driver.

The shoe rest 92, Fig. 1, is secured at 93 upon Van Vadjustable support 94 1vri'iich is connected to a bracket 95 extending from the head frame. The support 94 may be appropriately connected to the bracket 95 adjustably by any suitable means, such for instance, as the clamping bolt 96, a suitable guidevvay 9iV being employed for properly guiding the support 91 in its adjinsting movement. Pivotally mounted at 9S to suitable lugs projecting from the shoe rest 92, is an auxiliary shoe rest 99, preferably one member being disposedV at. nach side of the shoe rest 92. Iivotally mounted upon the adjustable support 94 by means of the pin 100 is the two-arm lever 101, one Sarm of which is connected by a link 102 to the rear und of the auxiliary rest 99, as at 103. An adjusting bolt 10al or other suitable adjusting means may be provided to limit the swinging movement of the auxiliary shoe rest 99 upon its pivotal mounting 98.1fThe other arm of the tivo-arm lever 101 isconE nected at 1023 to a rod 106 which is itself connected at 10T to a member 108 pivotaliy mounted at 109 onen arm 110 secured to the driver controlling shaft 111. A spring norinaliy acts upon the member 108 to draw the rod 106 to the right, Fig. 1, or in other words, to Yhold the auxiliary shoe rest below the shoe rest 92. The spring device for performing this function may be of any usual construction, but in the present instance ofthe inventiomit comprises the spring 112 seated in a suitable Vrecess ofthe arm 110V secured to the driver vcontrolling shaft as indicated in Fig.,6,and a ypin 113 engages V,this spring and the member 108 to normally turn the Said Vn'iember clockwise, viewingFig. 6, the construction being such that when the auxiliary shoe rest is not pressed .upwardly by the introduction of a shoe, the parts willassmne the position indicated in Figs. 1 and 6. .Y

Extending' downward from the member 108 isa Vpin 114VZ which may oe suitably clamped to; said member by a bolt or Vscrew 115, Fig, 1. VThe pin 1111, when the member 10S is under control of the spring 112, and

no shoe is in the machine, normally stands as indicated in F ig. 5, in the path of Inovement of the tack separator slide or rack bar 116 and serves fo effectively lock or prevent movement of the tack separator; but upon presenting a shoe to the machine for the lasting operation, the auxiliary shoe rest 00 is turned about its Yiiivirtril"'mounting, thereby drawing the rod 10e to VVthe left, Fig, 1, andtnrning the member 10S contraclockvvisglig. 6. tothereby remove the pin 114: fromV the path of movement of the separator slide or rack bar 119 so that the separator or Vtack feeding means is then free to he operated. j

MountedV upon the main shaft 3 is the tack driver lifting cam 117, Fig. 2, adapted to engage the Vdriver bar 118, and raise it against the action 'of the usual tack driver spring. At the lower end of the driver bar 118v is the Vdriver 120, the end of which is adapted to Vpass into the opening 76 ofthe tack carrienrvvhen the latter has moved a tack into taekdriving position, and force the tack into the upper materials for securing them in lasteiiposition, i

lt is a feature ot the present invention that when Yno Yshoe is in the machine the tack driver be locked from performing its driving function and to this end, the driver bar 118 is provided with a notched portion 121, Fig. Q, adapted to be engaged by the end 199 of a spring actuated locking bolt 123 mount'- ed for movement in suitable Ways 124 of a bracket secured to the head frame. The spring 125, Fig. i2, may be conveniently ear riedv in a recess in the locking bolt123, one end resting upon the bottomof the recess andthe other end against an abutment 196. Thc'looking holt 123 extends outwardly and is provided with an enlarged portion 127, the shoulders 127* of which limit the'inward movement of the locking bolt, and such eniarged portion is connected to a part 128, Eig. 1, having a locking notch 120 to engage theloeking shoulder 130 mounted on an arm 1731 secured to the driver controllin shaft 111, the construction being` such t at the spring 125 norniaiiy acts to force the locking bolt 123 inte iocking engagement with the driver bar 118 as indicated in Fig. 2, and

in such position of parts the locking sh oulder 130 in engagement with the locking recess 129. Upon rotative movement of the driver controlling shaft 111, eontracloekwise, viewing Figs. 1 and 6. it will he apparent that the locking' bolt 123 will be withdrawn from locking engagement with the driver rod that tack. Y .Y

In VfnfderrtoV eifeetively unlock the driver when ashoe is in position in the machine, automatic means are provided, the parts of which are operatively related when al shoe isrplaced in the machine. To this end the member' 108 is provided with a projection the driver will then bepermitted to drive a 132, Fig. 6, which, when no shoe is presented for the lasting operation and the said member 108 is perforce vturned into the position indicated in Fig. 6 by its spring 112, is not in the path of an actuator 133 which has reciprocating lnoven'lcnt. In the present instance of the invention, the actuator Y133 is formed as a finger secured by suitable means such as the bolt 134 to the tack carrier slide 7a, the construction being such that when the tack carrier slide is reciprocatcd as hereinbefore described, the actuator 133 will move correspondingly and if a shoe has been placed in lasting position in the machine, the projection 132 on the member 108 will have been moved into the path of the actuator 133, thereby operatively associating the projection 132 and the actuator 133 and effecting movement of the driver controlling `shaft 111 to withdraw the locking bolt 123 from engagement with the driver rod 118.

From the construction described as one convenient form or embodiment of the invention, it will be noted that when a shoe is not presented to the machine, both the tack feeding means and the tack dri ver are locked against operative movement; but when a shoe presented to the machine, the member 10S will be moved as hereinbefore eX- plained, thereby unlocking the tack feeding means and rendering the automatic means operable for unlocking the tack driver, so that upon reciprocating movement of the carrier slide T11- the tack feeding means will first be operated to feed a tack to the tack carrier and upon further movement of the carrier slide in the same direction the tack driver will be automatically unlocked to permit it to drive the tack presented by the tack carrier.

Changes may, of course, be made in the various constructions and details of the invention as hcreinbefore explained, without departing from the true scope thereof as pointed out by the claiams; but the described construction has been found a convenient and good, practical form of the invention.
